When he was carried from the hospital to the waiting car by his dad Prince William, the world struggled to catch a glimpse of the little prince, who was bundled up in a cotton swaddle decorated with tiny birds.

And though the walk to the car lasted less than a minute, everyone had to know: Who was he wearing?

Style bloggers and fashion writers quickly identified the brand, and within four hours of George's appearance, the Brooklyn-based brand aden + anais's website had crashed. Within nine days, the company had 7,000 orders, a 600% increase according to The Associated Press.

Now, over 10,000 of the wraps have been sold, and the retailer's website visits have skyrocketed to nearly 2,000% more than its daily average in Britain, and 500% more in the U.S, according to the New York Daily News.

CEO of aden + anais Raegan Moya-Jones said she had no idea that her blanket was going to be Kate's choice for Prince George. In fact, she found out when a coworker brought her a picture.

“Not in a million years did I ever anticipate the future king of England was going to come out in an aden + anais swaddle,” Moya-Jones told the Daily News. “I was dismissive, because I really thought it was a joke.”

The affordable brand is also big with celebrities like "Parks and Recreation" star Amy Poehler, and Matthew McConaughey and his wife Camila Alves.

Of course, the craze for all things Kate and baby is not likely to die down as the tot gets older. Eventually, tiny boots, coats, and hats will be fawned over on parent blogs with the same gusto that Kate's every fashion choice is followed by fashionistas.
